===Preliminaries===

* Make a new '''Android''' project with ''n'' = 7 following [[CISC181_F2017_NewAndroidStudioProject | these ]] instructions through step 6.  On step 7 "Select form factor...", switch over to step 4 on the Android developers page tutorial  [https://developer.android.com/training/basics/firstapp/creating-project.html here] and complete through step 6 which ends with "...click '''Finish'''".  Make the activity be called "MyActivity".

===Instructions===

First, make the empty activity project as described above and confirm that you can build and run it -- either on the emulator or an actual Android device as explained on the next page [https://developer.android.com/training/basics/firstapp/running-app.html "Run Your App"].  

Second, take the empty activity project and modify it to become a very simple "rock paper scissors" generator as detailed below:

# Change the layout in <tt>activity_my.xml</tt> to a vertical <tt>LinearLayout</tt>, similar to [http://developer.android.com/guide/topics/ui/layout/linear.html this example]
# Change the old <tt>TextView</tt> that was printing "Hello, world" to say "Click the button below to get a new shape".
# Add an <tt>ImageView</tt> underneath, centered laterally, that initially shows a rock, paper, OR scissors image.  Find your own for these, cropped and scaled to 250 x 250, and put them in <tt>res/drawable</tt> with the names "rock.png", "paper.png", and "scissors.png".  Here's some help for [http://developer.android.com/guide/topics/resources/drawable-resource.html drawable resources]
# Add a <tt>TextView</tt> underneath the image which acts as a caption, saying "Rock" if the image is a rock, "Paper" if it's paper, and "Scissors" if it's scissors.  The caption should be centered laterally.  
# Finally, add a centered <tt>Button</tt> under the caption.  This button should be labeled "New" and when pressed causes another random selection which (possibly) changes the image and caption above .  The caption text should be set not through resources but instead by using <tt>setText()</tt> in <tt>MyActivity.java</tt>, and something similar should be done with the image.

''Note'': Do NOT make changes to any other XML resource file besides <tt>activity_my.xml</tt>. 

Here is a screenshot of a sample program that satisfies the above requirements (except it should say "MyLab_7"):
